I'm trying to learn how to program animation by first taking pics of successive rame images, say, of a person running in place, or someone swinging a golf club, or whatever. You get the idea.
Now I want to crop these images at the same size in PS CS3 and then put them
in a tiled pattern, say 1x8, and save it as one bitmap image. My program will
then display the first tile, then the second, third, etc., and loop over. So if I
have 10 images of 200x400, my 10-tile image will be 2000x400.
When cropping, what's the trick in "automatically" choosing the reference
point so the animated image doesn't shake left-right, or up-down? IOW, if the first tile is cropped so the subject has less offeset from the left edge
as the next tile, the subject will seem to "jerk" to the right. Again, "automatically" is the operative word here, or at least a tool that pics the
center of the crop? I know I can press alt, then mouse-drag so the crop rectable expands fromt eh pointed pixel, but I still have to point the pixel (manual).
Make sense? Thanks.

As Mike said, try auto align layers first.
Just one other thing, instead of using a filmstrip type file, will your animation program not allow you to import Photoshop files? The reason for asking is that it may be more future resistant/flexible if you have each frame of the animation on individual layers.
I don't have an "animation program," I'm trying to write one, say in Java for example. I like your idea of being using layers so I'll google it, but do you have links handy you can share? Will this idea work over a network where the program has to download the image(s) on the fly? IOW, the files have to be small.

No, I don't have any links. The reason I know this is because Premiere CS4 doesn't accept filmstrip files anymore. Previously, you could export between Photoshop and Premiere using filmstrip files, which were basically all the video frames sequenced in a big bitmap.
Although Photoshop will still open filmstrip files, there is no easy way to export them in a format accepted by Premiere, and because it's just a big bitmapped file, there is no easy way to split them into individual layers.
It may be worth you googling "Photoshop animation" for some ideas, because from about CS2 onwards, they had basic animation included, if I remember correctly. If you are developing software, it may also be worth researching "Toon Boom", as you may also get some ideas here and also Flash of course.
Not being a software developer, I am afraid I can't really help you, as I would imagine that you know more than I do.
